VESSEL PROPELLING AND CONTROLLING DEVICE.

Application filed May 31, 1922, Serial No. 564.905. Renewed August 26, 1924. 1

To all whom it may concern:

Be it known that I, Amines JuilAN Earn. RYLANDER, a subject of the King of @weden, residing at Katarina Kyrkobackc '2, Stockholm, in the Kingdom of Sweden, have invented -certain new and useful Improvements in Vessel Propelling andfiontrolling Devices, of which the following is a specification.

This invention relates to' vessel propelling and controlling devices, and is particularly directed to the manner of controlling the speed and direction of a craft, to which an outboard motor is attached, and to the man ner of cooling the motor.

In the accompanying drawing which is to be taken as a part of this specification, and in which I have shown a merely preferred form of embodiment'of the invention:

Figure 1 is a side elevation of an out board motor constructed in accordance with the provisions of this invention.

Fig, 2 is a'plan view of a part of the speed and direction controlling arrangement.

Fig. 3 is a vertical section of a part of the device on the line 33.

Referring to the drawings, 1 indicates the motor which may be of any suitable or usual construction, and 2 the main standard, 39 through which the driving shaft 3 rotatably extends. The main standard 2 is turnnbly supported in a bracket clamp (not shown), which is detachably connected to the heck of the craft in any suitable manner. The standardQ surrounds the upper part of a sleeve or. tube t that is rigidly secured to the motor 1 and in its turn surrounds the driving shaft 3. The driving shaft is by a bevel gear 5 in the usual manner connected to a hollow propeller shaft 6, to which the propeller 7 is secured. The gear 5 and the front part of the shaft 6 are enclosed in a cap 8.

Rigidly attached to the tube 4 and the cap 8 is a substantially U-shaped, vertical frame 9 facing the propeller with its open part. To the vertical rear part of this frame 9 are hinged two plates 10 and 11, and to- 12 lie in the collapsed position between the plates 10 and 11.

Links 13are pivotally connected, as at 15, to horizontal groove shaped parts let of the plates 10 andv 11 respectively, and are also pivotally connected to a rod 16 that passes through the hollow propeller shaft 6 and on its forward part is formed as a rack 17. The grooves it are shown integral with the plates 10 and ll and formed by a curvature of the plates. The rack gears with a pinion l8 secured on the lower end of a vertical rod or tube 19, to the. upper end of which is secured opinion 20 gearing with a rack 21 on a slide 22, that is slidably mount ed in a bracket 23 extending from the main standard 2. Another rack ill on the slide 22 gears with a toothed segment 25 pivotally supported, as at 26, by consoles 27 on the bracket 23. Rigi'dly connected to the segmcnt 25 is an arm 28 ending in a handle 29.

The parts 23, 28 and 29 form in conjunction a steering lever or tiller, by which the outboard motor is turned as a whole for steering purpose.

Preferably the vertical tube 19 is connected to the cooling jacket of the motor 1 at its upper end by a tube 30, and at its lower end connected to awater-circulating pump 31 by any suitable channel system in the cap 8.

On lifting or lowering the arm 28, the tube "l9 will be rotated and the rod 16 forced to slide in the hollow propeller shaft 6. By means of the links 13 the plates thereby are opened or collapsed. in their opened condition they form a pocket that deflects the water stream comingfrom the propeller, whereby the craft is reversed. In an intermediate position of the plates, the craft will be stagnant, although the propeller 7 rotates continuously.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

I am aware that prior to my invention collapsible reversing rudders have been made. I therefore do not claim such rudders broadly; but

I claim 1. In a collapsible reversing rudder, the

(ill

combination with two vertical rudder plates normally tlat in engagement with each other and hinged to each other at their rear edges, of upper and lower plates having their edges hinged to each other and to the. upper and lower edges of said rudder plates, said upper and lower plates being hingeable inwardly and covered by said rudder plates in their collapsed position.

2. In a collapsible reversing rudder, in combination, two vertical rudder plates normally flat in engagement with each other and hinged to each other at their rear edges, upper and lower plates having their edges hinged to each other and to the upper and lower edges of said rudder plates, said upper and lower plates being hingeable inwardly and covered by said rudder plates in their collapsed position, and means for opening and closing said rudder.

3. In a collapsible reversing rudder for vessels, in combination, two vertical rudder plates normally flat in engagement with each other and hinged to each other at their rear edges, a frame supporting said rudder plates and turnably carried by the vessel, upper and lower plates having their edges hinged to each other and to the upper and lower edges of said rudder plates, said upper and lower plates being hingeablc inwardly and-covered by said rudder plates in their collapsed position. and means for opening and" closing said rudder.

4. In a vessel propelling and controlling device, the combination of a collapsible reversing rudder, a propeller, a hollow propeller shaft, a slidable rod passing through said hollow propeller shaft and connected to said collapsible rudder, and means for moving said rod fore and aft.

53. In vessel propelling and controlling device, the combination of a collapsible re- \ersi'ng rudder, a propeller, a hollow propeller shaft, a slidable rod passing through said hollow propeller shaft and connected to said rudder, a rack on said rod, a pinion engaging said rack, a shaft supporting said inion, and means for rotating said shaft.

6. A vessel propelling and controlling device as set forth in claim 5, and wherein the pinion supporting shaft is tubular.

7. A vessel propelling and controlling device as set forth in claim 6, and wherein the tubular shaft is connected with the motor jacket at its one end and with the water circulating pump at its other end.

8. In a vessel propelling and controlling device, the combination of a collapsible reversing rudder, a rod connected to said rudder, a rack formed on said rod, a pinion engaging said rack,a vertical shaft rigidly supporting said pinion at its lower end, av pinion rigidly connected to the upper end of said vertical shaft, av rack engaging said last mentioned pinion, and means for moving said last mentioned rack fore and aft.

9. A vessel propelling and controlling device as set forth in claim 8. and wherein the vertical shaft is tubular and connected at its upper end to the motor jacket and at its lower end to the water circulating pump.

10. In a collapsible reversing rudder, the combination of two rudder plates normally flat in engagement with each other, grooves arranged in said plates, said grooves forming in section av U-shaped extension of the plates, links engaging said grooves and hinged to said plates, a rod pivotally connected to said links, and means for moving said rod fore and aft for opening and closing said rudder.

ll. A collapsible reversing rudder as set forth in claim 10, and wherein the grooves are integral with the plates and formed by a curvature 01"- the plates.

12. In a collapsible reversing rudder as set forth in claim 10, and wherein the plates are vertical, the combination with the plates of HD3139! and lower plates having their edges hinged to each other and to the upper and lower edges of the first mentioned plates, said upper and lower plates being hingeahle inwardly and covered by the first mentioned vertical plates in their collapsed position.
